Powder near Super Bowl appears harmless: FBI

NEWARK, New Jersey--A suspicious powder mailed to several locations in New York and New Jersey, including at least five hotels near the site of Sunday's NFL championship game known as the Super Bowl, appeared not to be dangerous, the FBI said Friday.

The agency said further testing was being conducted on the substance, but it is "within normal values."

White powder also was found in a letter sent to former New York City Mayor Rudolph Giuliani's business in New York City, where police said preliminary tests showed it posed no threat.

A federal law enforcement official, who wasn't authorized to comment publicly and spoke on condition of anonymity, said powder from one envelope tested positive for baking soda. It's not clear where that letter was sent.
